Russia has expelled diplomats from Germany, Poland and Sweden for participating in illegal rallies in support of Alexei Navalny, the Russian Foreign Ministry said on Friday, confirming previous reports.

According to the ministry, they were declared personae non gratae and will soon leave the country.

“The Russian side expects that in the future the diplomatic missions of the Kingdom of Sweden, the Republic of Poland and the Federal Republic of Germany and their personnel will strictly follow the norms of international law”, the ministry said.Initial reports from EU Observer, citing anonymous sources in the bloc, said that Russia had expelled the three diplomats. The decision was reportedly made after talks between Russian Foreign Minister Sergey Lavrov and EU High Representative for Foreign Affairs and Security Policy Josep Borrell who was visiting Moscow for the first time.

Soon after the publication, the Swedish Foreign Ministry confirmed that their diplomat had been expelled. Polish Foreign Ministry, in the meantime, said that Warsaw will expel a Russian diplomat in a tit-for-tat move, according to the Russian Ambassador to Poland.

German Chancellor Angela Merkel has condemned Moscow’s decision, believing it to be unjustified and “a step away from the rule of law”. The chancellor added that Berlin is not ruling out personal sanctions in response to the expulsion of the diplomats.

A source in Moscow told reporters that a Swedish diplomat had taken part in an unauthorized rally on Nevsky Prospekt in St. Petersburg on 23 January. The Swedish embassy said the diplomat had only watched the action. Russian Foreign Ministry spokeswoman Maria Zakharova, commenting on the actions of western embassies regarding uncoordinated actions in Russia and the presence of diplomats at the trial in the Navalny case, said that Moscow would “address every such case”.

Several unauthorized rallies were held in Russian cities on 23 and 31 January, organized in support of Russian blogger Alexei Navalny who returned to Russia from Germany where he had been undergoing treatment for what Berlin claims was “Novichok poisoning”, despite failing to provide evidence.

Protesters also took to streets on 2 February after Navalny was handed a three-and-a-half-year jail sentence, replacing his suspended sentence on the embezzlement case.

A number of Western nations, including the US, Germany, France and the UK called on Moscow to have the blogger released.

The Russian Foreign Ministry decried western reaction to the rallies as a “coordinated global campaign to contain Russia and interfere in its internal affairs”. Moscow intends to have “a serious talk” with Washington on the matter, spokeswoman Maria Zakharova stated.
